1. The student is providing a presentation to the class regarding concepts in pharmacodynamics. Which statement made by a student in the class best demonstrates the need for further teaching?

a.	“Excretion and metabolism are components of pharmacodynamics.”
b.	“Receptor binding and potency are components of pharmacodynamics.”
c.	“Age and gender are components of pharmacodynamics.”
d.	“Routes of administration are components of pharmacodynamics.”

 

 

ANS:   B

Receptor binding and potency are components of pharmacodynamics.

Excretion and metabolism are components of pharmacokinetics.

Age and gender are biologic/physiologic variations.

Routes of administration are considered pharmacokinetics.

2. Which of the following best demonstrates the nurse’s understanding of how genetics influence drug response when considering individual variations in drug responses?

a.	Body weight
b.	Poor kidney function
c.	Cytochrome P-450 response
d.	A drug-drug interaction

 

 

ANS:   C

Cytochrome is dictated genetically and is very individualized.

Body weight may not necessarily be genetic.

Kidney function is a pathophysiologic response.

A drug-drug interaction is not a genetic response.

3. The nurse is administering morning medications. A patient questions the nurse, “How does the drug know where to go?” The nurse’s best response to the patient is based on the understanding that a drug that elicits only those responses for which it is given is considered

a.	Safe
b.	Effective
c.	Selective
d.	Predictable

 

 

ANS:   C

Selectivity defines a drug that elicits only those responses for which it is given.

There are no drugs that are considered safe by definition.

“Effective” is a term that describes a drug that is doing what it is expected to do.

A predictable drug response will have the mechanism of action that is expected from it.
